7″ Concrete Pro Hand Grinder Kit | Metabo W24-230 With Dust Shroud | Wheels & Handle

The 7” Metabo W24-230 Grinder-vac is a hand held concrete surface grinder that is designed to prepare concrete surfaces prior to application of epoxy, polyaspartic and urethane coatings and collect the dust at the same time while hooked up to a vacuum (vacuum attachment sold separately).

This heavy duty 15 amp 6,600 rpm 120V grinder is considered a “must have” for any industrial flooring contractor that applies floor coatings and needs to prepare the concrete or needs to remove old coatings, carpet glue and rough up the concrete or grind down high spots.  Hand-held units are great for smaller jobs or in combination with walk-behind grinders on larger projects

The 7” Grinder is designed to grind edges, tight areas, underneath fixtures or other areas where a larger floor grinder or shotblaster will not reach.  Production capacity of the 7″ grinder is rated between 150 to 200 sq’/hour with actual preparation and removal speed depending on conditions.

This setup comes with the U.S.SAWS Generation 2 dust shroud that can be hooked up to a variety of dust collection systems for dust containment, a Metabo W24-230 Grinder, Comfort Grip Loop Handle and (2) 7” 12 Segment Turbo Cup Wheels.

The 7″ Grinder kit comes with the US Saws G2 Convertible Shroud, designed to be the most durable and user-friendly dust shroud on the market. On the market for over 20 years, they took their classic dust shroud and made some adjustments for better dust collection and longer life. With the dust shroud, the concrete dust is extracted so that the operator may work without exposure to harmful dust. The convertible shroud allows the operator to grind against a vertical surface. A support flange allows the shroud to flex and keep a tight seal over uneven surfaces while preventing the cup wheel from making contact with the dust shroud.

To remove dust while using the 7″ concrete grinder kit and turn your standard Shop-Vac into an effective, industrial dust collector, removing most of the concrete dust that passes from your grinder or saw’s dust shroud before it reaches your vacuum’s filter see the US Saws Cycvlone Pre Separator
